Title: Production of bright false-twist textured polyester yarn
Inventor: AISAKA HIROYUKI
IPC: D06M101/16
Filed: 1988-03-18
Abstract: PURPOSE:To obtain the subject textured yarn excellent in deep color properties without any dimness and shininess, by false-twist texturing a highly oriented undrawn yarn containing a specific phosphorus compound and alkaline earth metal compound added thereto and reducing the weight of the resultant yarn. CONSTITUTION:(A) A phosphorus compound expressed by the formula (R<1> and R<2> are organic group; M is metal, etc.; n is 0 or 1) (e.g., trimethyl phosphate) and (B) an alkaline earth metal compound (e.g., calcium acetate) are added to a reaction system of (C) a polyester (e.g., polyethylene terephthalate) so as to provide 0.1-0.4wt.% total amount of the components (A) and (B) based on the component (C) and form internally deposited fine particles. The resultant polyester is then melt spun at >=4,000m/min take-off speed to afford an undrawn yarn having characteristics, such as 0.03-0.09 orientation degree in the amorphous part, etc. The obtained undrawn yarn is subsequently false-twist textured and subjected to weight reduction with an alkali to form many micropores on the surface. Thereby, the aimed textured yarn is obtained.

Title: Waveform shaping circuit
Inventor: HASEGAWA YOSHIHISA
IPC: H04L25/03
Filed: 1982-04-21
Abstract: PURPOSE:To shape the waveform of a superposed AC signal into an optimum waveform when a DC component varies by using a voltage generated by adding or subtracting a constant voltage to or from an input signal as the threshold voltage of a comparator for the waveform shaping. CONSTITUTION:The input signal consisting of the DC voltage Vdc and AC signal Vac is impedance-converted by a differential amplifier 21 and smoothed by a resistance R2 and a capacitor C1 before being inputted to the minus terminal of the comparator 22. The output signal of the amplifier 21 is inputted to the minus terminal of the comparator 22 through a resistance R1. In this case, a constant current source I1 is connected as shown by an arrow to flow a constant current, so the signal inputted to the plus terminal is the constant voltage DELTAV=I1R1 higher than the output of the amplifier 21. The threshold voltage is therefore DELTAV higher than the DC voltage to which the capacitor C1 is charged. Thus, the waveform of the signal Vac is shaped into the optimum waveform even when the DC voltage Vdc varies.

Filed: 1990-03-19
Abstract: PURPOSE:To continue the recording of a picture data by selecting the recording of a thermosensing recording section when the recording operation of a laser beam printer section is stopped. CONSTITUTION:When the residual amount of a toner is decreased on the way of recording in a laser beam printer section 7, the recording of the printer section 7 is stopped and an output from a toner residual amount detection section 71 is sent to a main control section 5 and it is displayed on a display section 92 of an operation display section 9.

Title: Fire detector
Inventor: ICHIKAWA NOBUYUKI
IPC: G08B17/12
Filed: 1993-03-25
Abstract: PURPOSE:To decide the degrees of flames regardless of the distance from each flame detected part and based on the relative relation between the flame degrees and the frequency components of flickering frequency bands of detected flames. CONSTITUTION:It is generally known that the flickering ways of flames differ from each other by the degree of each flame. Then it is defined from the results of experiments that the smaller degrees of flames the higher the flickering frequencies and vice versa. The output received from a flame detecting part 6 is amplified by amplifiers 1-3 of different amplifying center frequencies, and each output of amplifiers 1-3 is supplied to a deciding circuit 4. Thus the output of the amplifier 3 is relatively increased and the output of the amplifier 1 is reduced due to a fact that the smaller degrees of flames the higher the flickering frequencies. Meanwhile the output of the amplifier 1 is increased and the output of the amplifier 3 is reduced due to a fact that the larger degrees of flames the lower the flickering frequencies. Thus the circuit 4 decides the degree of each flame based on the preceding relative relation between the degrees of flames and the flickering frequencies.
